Adaptive fault-tolerant control based on boundary estimation for space robot under joint actuator faults and uncertain parameters

Since the joint actuator of the space robot executes the control instructions frequently in the harsh space environment, it is prone to the partial loss of control effectiveness (PLCE) fault. An adaptive fault-tolerant control algorithm is designed for a space robot system with the uncertain parameters and the PLCE actuator faults. The mathematical model of the system is established based on the Lagrange method, and the PLCE actuator fault is described as an effectiveness factor. The lower bound of the effectiveness factors and the upper bound of the uncertain parameters are estimated by an adaptive strategy, and the estimated value is fed back to the control algorithm. Compared with the traditional fault-tolerant algorithms, the proposed algorithm does not need to predetermine the lower bound of the effectiveness factor, hence it is more in line with the actual engineering application. It is proved that the algorithm can guarantee the stability of the closed-loop system based on the Lyapunov function method. The numerical simulation results show that the proposed algorithm can not only compensate for the uncertain parameters, but also can tolerate the PLCE actuator faults effectively, which verifies the effectiveness and superiority of the control scheme.

Innovation Inhibitors in War: Overcoming Obstacles in the Pursuit of Military Effectiveness

What explains the pace at which militaries adopt new technology? We argue that the hierarchical structure and unique expertise requirements of military organizations combine to empower select individuals as ‘gatekeepers’ of innovation. These individuals acquire beliefs throughout their military careers regarding the nature and means of warfare that act to shape their attitudes towards new military innovations. By filtering, sidelining, and ignoring competing sources of advice and information, these officers actively inhibit the adoption of new, often advantageous, innovations. We develop this argument through the analysis of two cases: the delayed acquisition of breech-loading and repeating rifles by the Union Army during the American Civil War, and the failure of the US Army to adopt an adequate heavy-type tank in World War II.     

舰载火炮闭环射击效力在线评估方法

舰炮火力决策中要依据射击效力实时评估结果,对评估准确性有较高高要求。本方法针对火炮系统闭环校射技术的特点,利用跟踪雷达提供的弹目脱靶量,将弹丸脱靶量实测数据用于修正原解析算法得出的弹丸单发命中概率,修正多发弹丸累积毁伤概率。评估过程应用了已测量的弹丸脱靶量,与传统解析估算法相比,由于最大程度地利用了实测数据代替误差估计数据,具有较高的精度。     

Using Indigenous Forces in Counterinsurgency Operations: The French in Algeria, 1954–1962

While the importance of indigenous forces for successful counterinsurgency operations has long been recognized by great powers fighting local insurgencies, the factors that determine the performance of such forces have attracted relatively little scholarly attention. This paper aims to contribute to our understanding of those determinants through an examination of the role and performance of auxiliary indigenous units in French counterinsurgency operations during the Algerian War (1954–62). The findings presented here suggest some important lessons for those seeking to recruit and deploy effective indigenous forces in counterinsurgency operations.
